Patrick Walton	b886c157c1	Use 2-lane instead of 4-lane SIMD types for 2D vectors. Also, this commit rewrites the `add_fill()` method to stop using shuffle instructions, which can be slow and make the code overly complicated. The shuffle instructions have been removed from the various SIMD backends.	2019-06-26 16:38:37 -07:00

Patrick Walton	431dcf3d2e	Rename `pathfinder_geometry::basic` to simply `pathfinder_geometry`, and move the remaining code in that crate to a new crate, `pathfinder_content` The old hierarchy was confusing.	2019-06-21 10:06:19 -07:00
Patrick Walton	487577a11b	Add Metal support. This commit substantially reworks the `pathfinder_gpu` API to better support modern APIs like Metal. It should open the door to `gfx-rs`, `wgpu`, Vulkan, and D3D12 backends relatively straightforwardly. A new example, `canvas_metal_minimal`, has been added. Note that the new Metal shaders require a patched version of `spirv-cross` to build properly. An upstream patch is forthcoming.	2019-06-20 11:47:22 -07:00
